Which of these advances caused the fireplace to become the central feature of kitchens?
__evolution of culinary techniques cooking on an open fire was the earliest culinary technique.
__boiling, which evolved as the next technique for cooking food, led to the design of customized utensils.
__people in early settlements, such as the egyptians, used small vessels (cauldrons).
__they hung these vessels over a fire to absorb and concentrate heat for cooking.
__the egyptians also invented sealable storage silos to preserve surplus grains for many years.
__native americans used clay vessels for cooking and storing foods.
__they used these vessels long before european settlers arrived with pots and kettles.
__stone cooking pots, used for cooking maize, evolved about 7000 bc in central america.
__the pots were so heavy that they were often left permanently in the center of the cooking space.

i think there are more hurricanes in the summer because it is warmer and the weather causes the water to become heavier and the weather is denser or more humid. the spring would be better to visit the caribbean.

is there multiple choice or do you need like an essay answer?

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
